Empyrial Plate Empyrial Armor rules magic wither damage draw a card and discard card

[Karter]

I have a 1/1 creature equipped with Empyrial Plate (and/or enchanted with Empyrial Armor.) The creature has one wither damage on it -1/-1

I have one card in my hand,

I use Artificer's Intuition

does the creature die?

[Arix]

State-based actions kill the creature long before the ability resolves and puts a card into your hand.

[Karter]

what about cycling a card?

[Arix]

Same.

[Karter]

so am guessing its the same for Coral Helm?

also how about Drastic Revelation?

[Arix]

Same for Coral Helm, yes.

Drastic Revelation is different, though. In that case the creature is safe while the spell finishes resolving.
